Liver cirrhosis is characterized by hyperaccumulation of fibrous tissue components and is commonly observed in latter or terminal states of chronic hepatic diseases. In this study, the antifibrotic effects of GLM001 on liver cirrhosis were examined in bile duct ligated rats and patients with hepatic diseases. GLM001 (250 mg/kg rat weight/ day) was administrated to cirrhotic rats for 4 weeks and to humans for 14 weeks. Bile duct ligated rats significantly increased liver collagen content and biochemical markers of hepatic injury. Liver histology showed collagen fiber deposition was increased and the normal architecture was lost with large zones of necrosis being observed frequently. GLM001 administrated rats showed significantly decreased liver collagen content, and accumulation of collagen fiber in histological analysis. Patients, who were treated with GLM001, showed decreases in biochemical markers of hepatic diseases. These results demonstrate the usefulness of GLM001 as an antifibrotic agent for liver cirrhosis.

Cholethorax is a bilious pleural effusion caused by a pleurobiliary fistula or leakage of bile into the pleural space. Most cases of cholethorax arise from a complication of abdominal trauma, hepatobiliary infection, or invasive procedures or surgery of hepatobiliary system. However, we experienced a case of a patient with cholethorax of unknown origin. There was no evidence of pleurobiliary fistula or leakage of bile from the hepatobiliary system although we examined the patient with various diagnostic tools including chest and abdominal computed tomography, endoscopic retrograde cholangiopancreatography, tubography, bronchofiberscopy, hepatobiliary scintigraphy and video-assisted thoracoscopic surgery. Herein we report a case of cholethorax for which the specific cause was not identified. The patient was improved by percutaneous drainage of pleural bile.

A 61-year-old male who complained of right upper quadrant pain was referred to the authors for evaluation after his computed tomography suggested biliary adenocarcinoma. The lesion consisted of multiple cysts with papillary mass and peri-ampullay mass. The patient underwent an operation due to a clinical suspicion of biliary cystadenocarcinoma, but the pathology confirmed biliary papillomatosis (BP) after diagnosing intrahepatic papillary neoplasm with high-grade dysplasia and invasive adenocarcinoma with papillary neoplasm from the distal common bile duct to the duodenum. BP is a disease characterized by multiple papillary masses. Its cause has yet to be discovered. It commonly manifests as bile duct dilation but rarely as a ductal cystic change. Under computed tomography or magnetic resonance imaging, both the BP and the cystic neoplasm can show bile duct dilation and a papillary mass, which makes their differential diagnosis difficult. A confirmative diagnosis can be made through a pathologic examination. BP is classified as a benign disease that can become malignant and may recur, though rarely. Its treatment of choice is surgical resection. Laser ablation or photodynamic therapy can be used for unresectable lesions. In the case featured in this paper, biliary papillomatosis was difficult to differentiate from cystic adenocarcinoma due to diffusely scattered multiple large cystic lesions in the liver, and it was histologically confirmed to have become malignant with cystic duct dilation after the operation. This case is reported herein with a literature review.

In order to select probiotics having both a high survival rate and an ability to inhibit virulent pathogens, we have screened lactic acid bacteria and yeasts from Jeot-gal to examine their resistance to artificial gastric and bile juice. After being introduced in the artificial gastric acid for 2 hr, the isolated lactic acid bacteria and yeast were incubated for 24 hrs in the artificial bile juice. In particular, the strain ML 36, ML 128, and ML 178 survived the longest during 2 hr incubation period in the artificial gastric acid. All 3 strains of lactic acid bacteria, and 2 strains of yeast demonstrated higher growth rates than control in the artificial bile. In addition, the antimicrobial activity of lactic acid bacteria and yeasts was investigated to determine their efficiency as probiotic organisms. The lactic acid bacteria inhibited Gram positive and negative bacteria, while the yeast was marginally inhibited.

Purpose: The aim of this study was to describe our treatment experiences with patients who had acute abdomen (AA) with common bile duct (CBD) dilatation. Methods: The treatment outcomes in children with AA and CBD dilatation were retrospectively reviewed. According to the shape of the intrahepatic bile ducts on ultrasonography (US), the origin of the pain was estimated as choledochal cyst (CC) complication or choledocholithiasis in normal CBD. Patients with complicated CC underwent surgery, and patients with choledocholithiasis in a normal appearing CBD underwent symptomatic treatment initially. Results: Of the 34 patients, 30 (88.2%) were female. The mean age of the patients was $6.4{\pm}4.9$ (range, 0.8-17) years. Seventeen (50.0%) patients had CBD stones and 17 (50.0%) did not. Surgical treatment was performed in 20 (58.8%) patients, 2 of whom underwent preoperative stone removal with endoscopic retrograde cholangiopancreatography and an operation. Conservative treatment was applied in 12 (35.3%) patients (8 with and 4 without stones), 1 of whom developed symptom relapse and underwent an operation. Among the 8 patients with CBD stones, 4 (4/17, 23.5%) had complete resolution of the stones and recovery of the CBD diameter after conservative treatment. US findings of patients with stone showed a fusiform or cylindrical shape of the CBD in 14 (82.4%) patients. Conclusion: The presence of stones in the distal CBD and the US features of CBD dilatation may be helpful to diagnose and treat the causes of biliary dilatation. Conservative treatment can be considered as initial therapy in patients with uncomplicated CBD dilatation with stone.

Three cases of extrahepatic bile duct disorder were presented. Two cases, a dog and a cat, were related to the obstruction of the extrhepatic bile duct, the other dog was affected with the gall bladder rupture. The clinical signs included anorexia, abdominal distension and vomiting. The laboratory test represented increased hepatic enzymes. On the radiography, hepatomegaly was seen in the obstructive cases, and ascites could be seen in the ruptured case. On the Ultrasonography, dilated gall bladder and extrahepatic bile duct were found in the obstructive cases, and there were ascites, indistinct gall bladder wall, dilation of gall bladder and extrabiliary tract, increased mesenteric echogenicity in the ruptured case. All presented were taken medication, surgical foreign material removal, or cholecystectomy showed complete recovery.

Lactic acid bacteria were isolated from piglets and chicken and characterized. Lactic acid bacteria showing resistance to low pH and bile, adhesion to intestinal epithelium cells, and the inhibition of Escherichia coli and Salmonella spp. were identified as Lactobacillus acidophilus. L. acidophilus PF01 survived for 2 h in MRS broth adjusted to pH 2. L. acidophilus CF07 was less resistant than L. acidophilus PF01 to pH 2, but survived at pH 2.5 for 2 h. Both of isolates were able to grow in MRS broth containing 0.3% (w/v) bile, with L. acidophilus CF07 being more tolerant to bile than L. acidophilus PF01. L. acidophilus PF01 and CF07 adhered specifically to the duodenal and jejunal epithelium cells of piglet, and the cecal and duodenal epithelium cells of chicken, respectively. Both of isolates did not adhere to the epithelium cells of the various animal intestines from which they were isolated. When L. acidophilus was cultured with E. coli and Salmonella spp. in MRS broth, MRS broth containing 2% skim milk powder or modified tryptic soy broth at $37^{\circ}C$, L. acidophilus PF01 and CF07 inhibited the growths of E. coli K88 and K99, and S. enteritidis and S. typhimurium, respectively. Both of isolates were found to possess the essential characteristics of probiotic lactic acid bacteria for piglet and chicken.

Seventy eight bacterial strains were isolated from several jeotgals using MRS and M 17 agar media. The probiotic properties such as tolerance of extreme growth condition, production of antimicrobial compound, production of hydrogen peroxide, and enzymatic activity of bile salt hydrolase were investigated. DHK 4, 10, 21 and 74 strains showed_a strong tolerance property against extreme conditions such as low pH and 0.5% oxgall-supplemented medium. DHK 10 and 47 strains produced hydrogen peroxide on TMB agar plate. DHK 8 and 10 strains produced antimicrobial compounds onto MRS agar against E. facalis. DHK 4, 6, 21, 29, 33, 63 and 87 strains had high activities of bile salt hydrolase. Especially, DHK 10 displayed a strong probiotic candidate; the abilities to produce the antimicrobial compound, hydrogen peroxide, and bile salt hydrolase. All these strains are assumed to be useful probiotic candidates. Among 78, twenty seven strains which have probiotic properties were tentatively identified by 16S rRNA sequencing. Among them, 7 Lactobacillus spp., 6 Leuconosotoc spp., 2 Weisella spp., 1 Pediococcus sp., 1 Staphylococcus sp., 1 Enterococcus sp. and 2 Streptococcus spp. were tentatively identified.

This study examined the effects of Lactobacillus acidophilus ATCC 43121 (LAB) on cholesterol metabolism in hypercholesterolemia-induced rats. Four treatment groups of rats (n=9) were fed experimental diets: normal diet, normal $diet+LAB(2{\times}10^6\;CFU/day)$, hypercholesterol diet (0.5% cholesterol, w/w), and hypercholesterol diet+LAB. Body weight, feed intake, and feed efficiency did not differ among the four groups. Supplementation with LAB reduced total serum cholesterol (25%) and VLDL+IDL+LDL cholesterol (42%) in hypercholesterol diet groups, although hepatic tissue cholesterol and lipid contents were not changed. In the normal diet group, cholesterol synthesis (HMG-CoA reductase expression), absorption (LDL receptor expression), and excretion via bile acids (cholesterol $7{\alpha}-hydroxylase$ expression) were increased by supplementation with LAB, and increased cholesterol absorption and decreased excretion were found in the hypercholesterol diet group. Total fecal acid sterols excretion was increased by supplementation with LAB. With proportional changes in both normal and hypercholesterol diet groups, primary bile acids (cholic and chenodeoxycholic acids) were reduced, and secondary bile acids (deoxycholic and lithocholic acids) were increased. Fecal neutral sterol excretion was not changed by LAB. In this experiment, the increase in insoluble bile acid (lithocholic acid) reduced blood cholesterol level in rats fed hypercholesterol diets supplemented with LAB. Thus, in the rat, L. acidophilus ATCC 43121 is more likely to affect deconjugation and dehydroxylation during cholesterol metabolism than the assimilation of cholesterol into cell membranes.

We performed bromodeoxyuridine (BrdU) staining to observe the proliferation pattern of epithelial cells on the biliaJy mucosa in Clonorchis sinensis infection. Albino rats were infected with 100 metacercariae each and their livers were processed for histopathological observation after BrdU injection. Five to six sites in the liver of a rat were selected for paraffin section, and stained immunohistochemically to visualize BrdU incorporating cells. The flukes were mainly in the common bile duct and right or left hepatic bile ducts. The proportion of stained epithelial cells in the infected bile ducts where the worms were found on the section was 2.9-10.2% at 1 week after infection. 7.3-12.8% at 2 weeks, 7.3-13.4% at 5 weeks, and 8.4-14.8% at 15 weeks while in the non-infected ducts o to 2.7% cells were stained. The stained cells were mainly at the base of the mucosal layer. It is suggested that mucosal epithelial cells of the bile ducts infected with C. sinensis become hyperplastic mainly by direct and local stimulation of the worms.
